If you already own a blue bell tree (Paulownia tomentosa), you do not have to worry about propagation. The imperial tree automatically ensures that its species does not die out. The seeds are particularly widely scattered, so that numerous bluebell trees shoot out of the ground in the vicinity and in return you should take care to remove the seeds in good time. For all those who still want to buy this pretty plant from the Far East, there are tips for species-appropriate propagation below.
The blue bell tree can be propagated in the following ways:
❶ Blue bell tree - propagation through cuttings
Gardening laypeople will also be able to reproduce a blue bell tree with the help of cuttings. The only problem is that there should be an imperial tree nearby. The cuttings are cut in autumn. This can be done as part of pruning measures. If a neighbor is there, he will surely be ready to transfer some cuttings.
The cuttings should be about 20 centimeters long and not too woody yet. It is also important to ensure that there are several eyes are on the shoot. This is where the leaves come out later. Immediately after the cut, the branches are placed in a planter filled with a nutritious and loose substrate. Now a little patience is required. The plant pot is placed in a bright and warm location and consistently moist, but not kept wet. The cuttings overwinter in the house and form roots over the winter. In spring, when night frosts can no longer be expected, the planter can be placed on the balcony or terrace.
The propagation by cuttings at a glance:
- Cut the cutting
- Prepare the planter
- Insert cutting
- Place the cutting warm and bright
- Keep the cutting moist
- Winter cuttings
- Wait for root formation
- Bring cuttings outdoors in spring
❷ Blue bell tree - propagation by seeds
The bluebell tree usually grows in its own hands. The seeds fall to the ground and are carried away by the wind. Thereupon a number of young plants grow on their own lawn or on the property of their neighbors. If an imperial tree already exists, propagation is not an issue.
If you want to grow a blue bell tree, you can collect the seeds from existing trees or purchase them from specialist shops.

It is best sown in February. The seeds are grown in flat growing trays. Peat is the best substrate. The seeds are spread on the substrate without being covered with soil. The seeds must be kept evenly moist during cultivation. However, waterlogging must not occur.
" Tip: If the planter is covered with a foil or glass cover, the germination process is accelerated.
Covered planters should be aired regularly, otherwise mold can form. The seeds germinate in a bright and warm location after about a week. Once the seedlings have grown about five centimeters, they should be separated and transferred to separate planters. Now the young plants are gradually getting used to being outdoors, initially only during the day. If late frost is no longer to be expected, the planters can spend the summer on the balcony or terrace.

Propagation methods with their advantages and disadvantages
|Propagation by cuttings||Cuttings can easily be obtained from existing plants. The propagation method is simple and promises high chances of success.||The cuttings are cut in autumn and have to spend the winter warm and bright until roots form. A plant must be available to be able to obtain cuttings.|
|Propagation by seeds||Sowing is easy and several plants can be grown at the same time. Germination begins quickly. Seeds can be obtained from existing plants.||If there is no plant, the seeds must be purchased.|
" Tip: The easiest way to get a blue bell tree is to dig a young plant out of the ground and put it in a planter at home. If the plants grow nearby, this will not be difficult. When digging out the young plant, care should be taken to avoid damaging the delicate roots.
What happens to the young plants?
Young plants do not yet have a fully developed root system and are more sensitive than an adult blue bell tree. The little plants need a lot of sun from the start. A protected outdoor location is an advantage. Young plants should be watered regularly. It is particularly important to ensure that there is no waterlogging in the planter.
A drainage in the bottom of the vessel protects against waterlogging, since the irrigation water can drain away better. Young plants are cultivated in the house until late frosts no longer threaten. In the first two years after planting, the small imperial trees need winter protection. As soon as the first frosts are predicted, the planters are brought into the house and hibernated bright and dry at around eight to ten degrees.
" Tip: Young imperial trees are not hardy. It is therefore advisable to keep containers in the first few years.
